This post will be getting updates from time to time with additional information and maybe some FAQs.

FAQWhat is the Validation step I see every time I try to create a new rule?-It's a feature that aims to automate the URL splitting process. It requires the adminCP URL to have the same scheme, host and base (XenForo installation) path with the inserted one.---------------------------------------------------------------------------------------------------------------I can move the rules up and down, why?-The rules nearest the top have higher priority than the following ones.---------------------------------------------------------------------------------------------------------------I can not find the control panel, what's wrong?-Only Super Admins and administrators that have the "Manage styles, style properties, and templates " permission are allowed to use this add-on.-----------------------------------------------------------------------------------------------------------------How exactly the rules and sub-rules are structured?

Main Rule

URI

Scheme

Host

Base Path: the path of your XenForo location, if any

Rest Path: the remaining path (full path - base path)

Query

Device

Browser

User Agent regular expression

User

User Id(s)

Style(s)

ScreenshotsIn the above screenshots you can see how to assign a specific style (in our case Black n' White) to a specific thread.

@Calamity James As I don't have a personal forum included in the tapatalk database to test with, check if the attachment included in this post fixes the issue. If it does, I'll update the main add-on with the fix

So if I want a dedicated Category page, or a specific forum list page, or a usergroup set of Profile pages - I could assign a certain design to a unique page? or to a group of pages?

Think of it like this. In your post, you' re talking about 3 pages. Every page has a URL. If we wanted to assign a certain style to a page, we' d use the URI sub-rules and create a main rule for that page.

Here, I am creating a URI-only based rule with a specific style assigned to my profile page, any visitor browsing that page will see that specific style.

Let's say I don't want everyone to see my cool user profile style, but only a few trusted members of a specific User Group, let's say Moderators.
I'll need to select/check that User Group inside the User Group sub-rule field.

If I wanted my Moderators to see that style only by browsing from a mobile device I would set the isMobile sub-rule to 'Yes'.

Notice the asterisk on the right side of the User Group label. As we haven't yet checked a group, that asterisk notifies us that the User Group criteria will not be checked to assign the style.

This seems to create the opportunity for Style creators to make xenforo even better.
If I bought a Style from DesignerX ... how would they also include page / node / URL specific styles ?
Would they send me an .xml file and I would upload it ?
Is it not possible ?

A designer needs to create a separate style and send you the .xml file. The only one who can assign that style to a specific page / node / URL is you.
